"Your excellency, we cannot do as you ask," Hal answered firmly. "What I have stated is absolutely true, and if only you will favor me by reading the letter which I have in my pocket, you will be assured of it."

"Give it to me. One of you take it from his coat," said the colonel shortly.

The order was obeyed by José, and the letter handed to the colonel. Instantly he tore the envelope open, and scanned the contents.

"Yes, it is as you stated," he said. "I am more inclined to believe you."

"Pshaw! And you will allow two dangerous spies to escape because they are of the same age as your sons!" exclaimed José d'Arousta. "It is madness! It is folly!"

He had been standing close beside the table, following the interview between Hal and the colonel with the greatest attention; and now, seeing that it had turned in favor of the prisoners, he started forward, and interposed in a way which soon brought him a reprimand.

"Señor, you forget yourself, and in whose presence you stand!" the colonel cried angrily, turning upon him. "Have a care, Señor Capitan, for I am your superior, and should you see fit to address me again in such an unbecoming manner, I will place you under arrest. Perhaps it might meet your deserts," he added significantly, "for there are tales told in Santiago of the doings of José d'Arousta and his irregulars. I have even heard it said that they are brigands. Have a care, I tell you, for I might even go so far as to look into this strange accusation as to an attack upon Eldorado."

José had met his match. He turned pale at the colonel's words, and retired from the table looking downcast. But his assurance quickly returned.

"Excellency," he exclaimed, "your pardon if I was too outspoken; but I wish our country all that is well, and therefore I say again that these two men are known to me. They are spies. Everything points to it, señor. If not, then why should they attempt to escape, particularly when one of them carries a letter, the contents of which will clear them? Depend upon it, that note was there for a set purpose, and to be used only as a last resource. Think of their revolvers, too. Pah! Were I in your place I should give them till dawn, when they should face a corporal's picket, and meet the fate of all who take to the calling of a spy."

He ended an impassioned speech with a glare of hatred at Hal, and then stood closely scrutinizing the colonel's features, to see, if possible, what effect he had made, turning, however, every other moment to look again at Hal, with eyes which even now were beginning to light up with triumph.
